FAUCET.

Application filed March 5, 1925. Serial No. 13,215.

To allfwkom 2'# may comm:

Be it known that l, JAMES C.` Ross, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Faucets, of which the following is a specification.

This invention relates to faucets of the yautomatically closing type.

The object of the present invention is the provision of an improved faucet of this nature which will be of compact construction, eiiicient in operation, and with the op-v erating p arts readily accessible for renewal and repalr.

its embodiment now preferred by me; and

Fig. 2 is a horizontal section on line 2- 2 of Fig. l, looking upwardly.

saiddrawing, the reference numerals Aand 2 designate the upper and lower members, respectively, of the faucet body, the

same beingdetachably connected with eachA other by inter-engaging screw threads.

To facilitate`uniting and separating oi fsaid members, the threaded portions of the body members are;l slotted longitudinally as at 38 (Fig. 2) to aii'ord incomplete screw threads, as 26 and 261, on the respective members. Such incomplete threads, circum-erentially of the respective members, bein of lengths slightly less than the widt s of Asaid slots, thus permitting 'the members, being joined by rst inserting the '.'threads of one member mto theslots of the other member and then turning themember 1 into engaged relation with the member2. 18 reprents a' gasket to prevent leakage at the joint between the bodymembers.

In l with the member 2 is a nipple 37 which 1s externally Ascrew threaded for engaement Awith a service pipe. (not shown)A an Within the chamber 33 of the body mem.

ber 2, is an extension or nozzle 36 of the nipple 37, sald nozzle element projecting upwardly from the base 25. Provided above sa1d base 1n the peripheral wall of the element 36 is one or more apertures 24 for the escape of water from the chamber 33 when it is desired to drain the latter. The body member 1 is provided at one ,side of its chamber with an 'outlet 16 which com-' municates with the inlet 17 of a spout 8 whlchls rigid with said member.

, The member 1 is formed with a cylindri, cal neck 40, the same being externally screwY threaded for engagement with the internal Vthreads of a bonnet 9 which serves as a gland for retaining packing (not shown) in the space 12 above a washer 13 which is 'ml y seated upon the top'of 'the neck 40. This neck is provided with internal| screw threads Y that are engageable with the screw threads of an operating stem 14 which' extends throughthe bonnet 9 andthereabove is taan extension 22 through which is a passage 19 aiording communicationbetween the referred to chamber and radially disposed ducts 28 communicating with the chamber 33.

Below the ducts 28, the extension 22 is bored as at 31 from its underside to rovide a cavity, itting within which, or near y so, is a cynlindrical piston 3 having an up r cylin -cal portion 30 of relatively sma er diameter which extends through a circular open1ng21 provided in the wall above the bore 31.- The piston 3 and the portion 30 constitute the valve roper of the faucet. Such valve is provided with a stem 4 which extends through a guide hole 15 of the body memberl into position to been d by the operating stem 14. To enable sai Yvalve to function, the same is formed, as shown, with a peripheral bevel 29 which is enga le directly against a. bevel seat 27 provi ed at v the lower end-of the passage 19.

The `illustrated construction above described, with regard to the valve seatingsurface 29, is nowpreferred b me, butV it is not intended to limit myse specifically thereto, as known valves such as that oonventionally designated as a Fullers valve may in lieu thereof be mounted upon the stem 4 to engage the seat 27.

The illustrated valve is hollow to afford a cavity 34 into which the water supply nozzle 36 projects, the lower portion of this cavity 34 being of a diameter greater than said nozzle to furnish an annular conduit 23 leadin from the nozzle into the chamber 33. .'I e Space 31 surrounding the valve part serves as a receptacle for a body of water which acts against the annular shoulder 2O of the valve and, subject to the escape of water gradually through the interstice 32 from such receptacle, regulates the closing of the valve with respect to its seat 2 In other words, the pressure of water dischargin from the nozzle 36 effects the closing of t e valve, but which is'restrained by the dash-pot action of the gradually lessening body of water within the space 31.

In operation, the valve is shown as held in its open position by means of the operat- 1 ing stem 14 and, thus arranged, water supplied under ordinary service pressure will be discharged through nozzle 36 and cavity 34 into the chamber 33, and thence the water passes through ducts 28 and passage 19 into the chamber 35 whence it is delivered through the spout 8. For closing the valve the operator regulates the handle 6 to retract the operating stem 14, whereupon the service water from nozzle 36 impels the valve 3-30 upwardl against its seat 27 thereby stop-ping the ow of water from the chamber 33. Such valve closing action is, however, done in opposition to the effective resistance afforded by the water within the cavity 31, resultin in the slow, steady, and noiseless closing o the valve.

l. In a faucet.l the combination with the body having a water receiving chamber provided with water inlet and outlet openings respectively at the lower and upper portions of the chamber, a valve seat`at said outlet opening, a cylinder rigid with the' body, said cylinder being of less diameter than the chamber and in spaced relation `from both of said openings to afford therebetween a communicating passage eXteriorly 0f the cylinder, a valve for said seat, a hollow piston rigid with the valve and operating within the cylinder for regulating the closing movement of the valve, and manually vactuated means for eecting an opening movement of the valve.

2. In a faucet, a body having a water receiving chamber, a cylinder rigid with the body and located in spaced relations with respect to the top and bottom ofthe chamber, said cylinder having a top wall provided with a centrally disposed aperture, a water outlet and a valve seat therefor located above said cylinder wall, an inlet nozzle extending upwardly into the-chamber below the cylinder, a piston operable within the cylinder bore and having an extension extending through the wall aperture of the cylinder to serve as a valve for said seat, said valve being moved into closing position by the impact of water from the orifice of said nozzle subject to the restrictive action of a body of water between the piston and said cylinder wall, and manually operable means for effecting the opening movement of the valve.

3. In a faucet, a body comprising two chambered members separably connected together one above the other, the lower of said members having a water-inlet nozzle extending into its chamber, the upper member having an extension -depending into the chamber of the lower member and having a cylinder bore at its lower extremity, communicative connections between the body chambers said connections including a passage extending downwardly from the upper chamber to a valve seat and thence to tle upper ortion of the lower chamber, a piston acting within said bore and having an extension adapted to serve as a valve with respect to said seat, a stem extending from the valve through said passage and the upper chamber of the body, said piston having in its underside a cavity for the impact of water frc .n said nozzle to effect the elevation of the piston and the valve into closing relation with said seat, and manually actuated means engaging against the end of the valve stem for effecting the opening movement of the valve with respect to the seat.

Signed at Seattle, Washington, this 21st day of February, 1925.
